[0045] Referring to FIG. 1-FIG. 18, this application provides a
humidifying device, the humidifying device mainly realizes the
purpose of humidifying by spraying. Therefore, the humidifying
device in this embodiment can also be other devices for realizing
the purpose of humidifying by using the spraying principle.
[0046] The humidifying device of this application includes a shell
10, and an air duct 5 and an air blowing apparatus (not shown)
disposed in the shell 10. A mist outlet channel 11, and an
atomizing cavity 3 and a heating cavity 4 communicated with the
mist outlet channel 11 are disposed in the shell 10. The air duct 5
includes a first air duct 51 communicated with the atomizing cavity
3 and a second air duct 52 communicated with the heating cavity 4.
The air blowing apparatus is provided with an air outlet member 61
for outflow of an air flow, and the air outlet member 61 is aligned
with the first air duct 51 and the second air duct 52, and is
configured to supply a first air flow to the first air duct 51 and
supply a second air flow to the second air duct 52.
[0047] When humidifying device operates, the first air flow enters
the atomizing cavity 3 through the first air duct 51 to form an
atomized air flow, the second air flow enters the heating cavity 4
through the second air duct 52 to form a heated air flow, and then
the atomized air flow and the heated air flow enter the mist outlet

[0054] The following describes the mounting position relationship
and specific structures of the air duct 5, the air blowing
apparatus, the atomizing cavity 3, the heating cavity 4, the water
tank 1, and the seat 2 of the humidifying device.
[0055] Referring to FIG. 3 and FIG. 4, the air duct 5 includes a
first air duct 51 and a second air duct 52. The air duct 5 has an
elongated shape as a whole, and an air outlet member 61 extends
into the air duct, so that the air duct is separated by the air
outlet member 61 to form a first air duct 51 and a second air duct
52.
[0056] Specifically, the air duct is jointly formed by the seat 2
and the water tank 1. The water tank 1 is provided with a water
tank bottom wall 12 near a side where the water tank 1 is located.
The water tank bottom wall 12 is provided with two spaced air duct

outlet 612 are arranged along an extending direction of the air
duct.
[0058] An opening size of the first air outlet 611 is greater than
an opening size of the second air outlet 612, so that an air flow
rate blown to the atomizing cavity 3 through the first air outlet
611 is greater than an air flow rate blown to the heating cavity 4
through the second air outlet 612, thereby ensuring that the
atomizing cavity 3 is the main mist outlet cavity.
[0059] Correspondingly, the depth of the first air duct 51 as a

duct 51 as a whole is greater than that of the second air duct 52,
and the depth of all positions of the first air duct 51 is not
strictly required to be greater than that of the second air duct
52, the depth of some areas may be greater than that of the second
air duct 52, and the depth of some areas may be equal to that of
the second air duct 52.
[0060] Again referring to FIG. 3 and FIG. 4, in a specific
embodiment, the air duct includes a first section 54 and a second
section 55, the first section 54 being recessed relative to the
second section 55 toward the side away from the seat 2, the air
outlet member 61 extends into the first section 54 and is disposed
close to the second section 55. In this case, the portion of the
first section 54 from the air outlet member 61 to the atomizing
cavity 3 forms the first air duct 51, and the second section 55
together with the portion of the first section 54 from the air
outlet member 61 to the second section 55 jointly forms the second
air duct 52. By disposing the first section 54 to be recessed with
respect to the second section 55 toward the side away from the seat
2, a depth of the first air duct 51 as a whole greater than the
depth of the first air duct 51 can be obtained, thereby matching
the flow rate of air flowing into the first air duct 51 and the
second air duct 52.
[0061] In addition, as illustrated in FIG. 3, the abutment of the
first section 54 and the second section 55 forms a transition
surface 56, which extends from the end of the second section 55
toward the side away from the water tank 1, so that the first
section 54 is recessed with respect to the second section 55. When
the air outlet member 61 is placed in the second section 55, the
second air outlet member 612 is aligned with and spaced from the
transition surface 56.
[0062] FIG. 5 illustrates a schematic structural diagram of another
water tank in FIG. 3. Referring to FIG. 3, the transition surface
56 may be a vertical plane formed by a vertical recess from the
side where the seat 2 is located, or may be, as illustrated in FIG.
5, an inclined plane with a certain slope. Preferably, the inclined
plane is inclined inward and extended from the side where the
second section 55 is located toward the side where the second
section 55 is located.
[0063] Referring to FIG. 3 and FIG. 5, the side of the water tank
bottom wall 12 facing the seat 2 is further provided with a support
plate 57, which is configured to enlarge the support surface
between the water tank 1 and the seat 2, so that the water tank 1
is more stable when mounted on the seat 2. The support plate 57 may
be provided at an interval with the air duct partition 53 or may be
integrally formed therewith, and the support plate 57 and the air
duct partition 53 may be integrally formed for convenience of
manufacturing.
[0064] It should be noted that in the structure of the water tank 1
in FIG. 3, the support plate 57 and the air duct partition 53 form
a U-shaped open structure, while in FIG. 5, the support plate 57
and the air duct partition 53 form a closed structure, specifically
being disposed in a square shape. However, the shape of the support
plate 57 and the air duct partition 53 as a whole is not
particularly limited and may be closed or open. When the support
plate 57 and the air duct partition 53 form an open structure as
shown in FIG. 3, the seat 2 is provided with a protrusion, which
abuts against the water tank bottom wall 12, and coordinates with
the support plate 57 and the air duct partition 53 to ensure the
stability of the installation of the water tank 1 on the seat
2.
[0065] In the humidifying device of this embodiment, the air duct
partition 53 is disposed on the seat 2, and the air duct 5 is
formed by the air duct partition 53, so that the space between the
seat 2 and the water tank 1 is fully utilized, and the air outlet
member 61 disposed on the seat 2 extends into the air duct 5, so
that one air duct is separated into two different air ducts in a
simple manner. The structure is simple and the implementation is
convenient.
[0066] It should be understood that in this embodiment, the first
air duct 51 and the second air duct 52 may not be formed by
separating one air duct 5, alternatively, the first air duct 51 and
the second air duct 52 may be disposed independently and
separately, and the positions and numbers of the first air outlet
611 and the second air outlet 612 are not particularly limited, as
long as the air flow from the air outlet member 61 can be blown
into the first air duct 51 and the second air duct 52
respectively.
[0067] Referring to FIG. 2, FIG. 7 and FIG. 8, the seat 2 is
provided with a heating groove 41, the opening of the heating
groove 41 faces the side where the water tank 1 is located, the
heating groove 41 is covered with a cover 42, and the inner wall of
the heating groove 41 and the cover 42 are surrounded to form a
heating cavity 4.
[0068] The heating cavity 4 is jointly formed by the cover 42 and
the heating groove 41, so that steam heated by water can be
accumulated in the heating cavity 4 without heat loss, and
therefore the utilization rate of hot mist is high. At the same
time, due to the isolation effect of the cover 42, the water
splashed out from the heating groove 41 can be prevented from
leaving the heating cavity 4, thereby protecting other parts of the
humidifying device.
[0069] Referring to FIG. 9 and FIG. 10, two different types of
covers 42 are illustrated. The shell 42 is provided with a first
opening 421, a second opening 422, and a third opening 423. As
illustrated in FIG. 2, the first opening 421 is communicated with
the second air duct 52, the second opening 422 is communicated with
the mist outlet channel 11, and the third opening 423 is configured
to supply water to the heating cavity 4. When the humidifying
device operates, the second air flow blown from the air outlet
member 61 flows into the second air duct 52 from the air outlet
member 61, then enters the heating cavity 4 through the first
opening 421 to form a heated air flow and then enters the mist
outlet channel 11.
[0070] The wall surface of the cover 42 away from the heating
groove 41 is a top wall of the cover 424, the wall surface in a
circumferential direction of the cover 42 is a cover
circumferential wall 425, the first opening 421, the third opening
423 are provided on the cover circumferential wall 425, and the
second opening 422 is provided on the top wall of the cover 424.
The first opening 421 is disposed aligned with the second air duct
52 and the second opening 422 is disposed aligned with the mist
outlet channel 11. The third opening 423 is preferably disposed at
one side edge of the cover circumferential wall 425 away from the
top wall of the cover 424, and the third opening 423 is formed by
providing a notch at the edge.
[0071] Referring to FIG. 6, a specific implementation of disposing
the first opening 421 aligned with the second air duct 52 may
include: the first opening 421 is aligned with an opening at one
end of the second air duct in the longitudinal direction, and the
air duct partition 53 is abutted against the circumference of the
first opening 421 to reduce the flow of air flow from the
circumference of the first opening to the outside of the second air
duct 52.
[0072] By disposing the second opening 422 aligned with the top
wall of the cover 424, the flow rate of the second air flow is
increased so that the hot mist can be rapidly blown out.
[0073] More specifically, still referring to FIG. 9 and FIG. 10,
the second opening 422 includes a plurality of rows of adjacently
disposed steam outlets 426 each having an octagonal shape.
Preferably, the sum of the opening areas of all steam outlets 426
is less than or equal to one eighth of the area of the top wall of
the cover 424, and the number of steam outlets 426 is greater than
or equal to ten. In this way, the heated air flow from the heating
cavity 4 can be ensured, and the shielding effect of the cover 42
can be sufficiently ensured, so that the noise in boiling water can
be reduced by the shielding effect of the cover 42.
[0074] Referring to FIG. 9, the top wall of the cover 424 has a
surrounding portion 427 that surrounds the second opening 422, and
the surrounding portion 427 is arranged obliquely with respect to
the vertical direction, so as to guide condensed water on the top
wall of the cover 424 and prevent noise caused by direct dripping
of the condensed water. It should be understood that, as shown in
FIG. 10, the top wall of the cover 424 may alternatively be
disposed entirely inclined with respect to the vertical direction,
which can also guide the condensed water in the top wall of the
cover 424. In this case, the "be disposed inclined with respect to
the vertical direction" is based on the position of the cover when
the humidifying device is in an operating state.
[0075] Referring to FIG. 2, FIG. 7, and FIG. 8, the seat 2 is
further provided with an atomizing groove 31, an opening of which
faces the side where the water tank 1 is located, and the internal
space of the atomizing groove 31 is communicated with the space
between the opening of the atomizing groove 31 and the water tank 1
to jointly form an atomizing cavity 3, that is, the atomizing
groove 31 forms part of the space of the atomizing cavity 3.
[0076] As illustrated in FIG. 2 and FIG. 11, the atomizing groove
31 is further provided with a muffler 32. And the muffler 32 is
disposed between the seat 2 and the water tank 1. The muffler 32 is
funnel-shaped, a smaller opening of the funnel-shaped muffler 32 is
a fourth opening 321, a larger opening of the muffler 32 is a fifth
opening 322, the fourth opening 321 is aligned with the opening of
the atomizing groove 31, and the fifth opening 322 is communicated
with the mist outlet channel 11.
[0077] The muffler 32 may be fastened to the water tank bottom wall
12, or to the seat. In an implementation, the muffler is fastened
to the water tank 1, as illustrated in FIG. 11, in such a manner
that a fixing plate 327 extends radially outward from the periphery
of the fifth opening 322, and the muffler 32 is fastened to the
water tank bottom wall 12 through the fixing plate 327.
[0078] It should be noted that since the muffler 32 is disposed
between the seat 2 and the water tank 1, a portion of the water
tank bottom wall 12 aligned with the atomizing groove 31 is
recessed toward a side away from the atomizing groove 31 to
facilitate the installation of the muffler 32, thereby forming a
receiving space 13, and the receiving space 13 and the atomizing
groove 31 jointly form the atomizing cavity 3.
[0079] Because a funnel-shaped muffler 32 is arranged above the
atomizing groove 31, water droplets excited in the atomization
process of the atomizing sheet can slide down along the side wall
of the muffler 32, thereby preventing the excited water droplets
from directly falling back to the water surface, and better
reducing the dripping sound generated in the humidifying process of
the humidifying device.
[0080] The muffler 32 has a circumferential sidewall 323 which is a
wall surface connected between the circumference of the fourth
opening 321 and the fifth opening 322 and surrounded in the
circumferential direction.
[0081] Referring to FIG. 4, at least part of the circumferential
sidewall 323 is located inside the air duct 5, a first ventilation
hole 324 is provided on the circumferential sidewall 323 located
inside the air duct 5, and the air duct 5 is internally
communicated with the muffler 32 through the first ventilation hole
324.
[0082] The muffler 32 may be coordinated with the air duct 5 by
directly be abutted on the air duct partition 53, or in another
manner. In an implementation, a circumferential sidewall 323 of the
muffler 32 is provided with extension plates 328 spaced away from
each other and extending outwards, the two extension plates 328 are
respectively abutted on the two air duct partitions 53, so that the
muffler 32 is provided at the opening of the first air duct 51
facing the atomizing cavity 3, and that the air flow blown from the
first air duct 51 mainly enters through the first ventilation hole
324 of the muffler 32 disposed in the air duct 5, thereby
preventing the air flow from being disturbed and making the air
flow utilization rate high.
[0083] It should be further understood that, in this embodiment,
not only the circumferential sidewall 323 of the muffler 32
disposed in the air duct 5 is provided with a first ventilation
hole 324, but also the whole circumferential sidewall 323 is
provided with a first ventilation hole 324.
[0084] The first ventilation holes 324 are provided in an elongated
shape extending from the side where the fourth opening 321 is
located toward the side where the fifth opening 322 is located, and
the width gradually increases in the extending direction.
[0085] It should be noted that in order to further enhance the
silencing effect of the muffler 32, a baffle 325 is provided at the
first ventilation hole 324, the baffle 325 extends from the side
where the fourth opening 321 is located toward the side where the
fifth opening 322 is located, and both ends of the baffle 325 are
respectively connected to both ends of the first ventilation hole
324 Both sides of the baffle 325 are spaced from the
circumferential sidewall 323 of the muffler 32, so that a second
ventilation hole 326 is formed between the baffle 325 and the
circumferential sidewall 323, and the second ventilation hole 326
is communicated with the first ventilation hole 324. The first air
flow flowing out of the first air duct 51 enters the muffler 32
through the second ventilation hole 326 and the first ventilation
hole 324.
[0086] It should be noted that the circumferential sidewall 323 and
the baffle 325 of the muffler 32 described above are defined as two
different parts. The baffle 325 and the circumferential sidewall
323 are integrally formed. It can be understood that the baffle 325
may not be provided.
[0087] A front projection of the baffle 325 on the circumferential
sidewall 323 of the muffler 32 can cover the first ventilation hole
324, so that water droplets do not drip directly from the first
ventilation hole 324 into the atomizing cavity 3 and generate
noise, but flow down the baffle 325. More specifically the baffle
325 is disposed outside the circumferential sidewall 323 and is
bent in a V shape. It should be understood that the baffle 325 may
be provided in the muffler 32, and the shape of the baffle 325 may
be another shape such as an arc shape, which is not specifically
limited here, as long as the condensed water can be guided into the
atomizing groove 31.
[0088] It should be noted that in this embodiment, the muffler 32
and the cover 42 may be provided at the same time, and either of
the cover 42 and the muffler 32 may be selected, or both may be
provided, which is not particularly limited in this embodiment.
[0089] Specific configurations of the atomizing groove 31 and the
heating groove 41 are described above, and the specific position
relationships of the atomizing groove 31, the heating groove 41,
the air outlet member 61, and the air duct are described
herein.
[0090] Referring to FIG. 8, a raised wall 21 is provided between
the atomizing groove 31 and the heating groove 41, and the
atomizing groove 31 and the heating groove 41 are separated from
each other by the raised wall 21.
[0091] The side of the atomizing groove 31 away from the heating
groove 41 is a first side 311, the side of the heating groove 41
away from the atomizing groove 31 is a second side 411, and the air
outlet member 61 is located between the first side 311 and the
second side 411. In this way, the length of the air duct can be
shortened, the flow time of the air flow is reduced, and the
humidification efficiency is high. Moreover, in this embodiment,
the air duct 5 is located at a side of the whole formed by the
atomizing groove 31 and the heating groove 41, so that the height
space of the humidifying device is not occupied, and the structure
is more compact.
[0092] It should be pointed out that the position of the air outlet
member 61 between the first side 311 and the second side 411 is not
strictly disposed in the middle of the first side 311 and the
second side 411, but also includes that an orthographic projection
of the air outlet member 61 at a vertical connection line between
the first side 311 and the second side 411 is located between the
first side 311 and the second side 411. In this embodiment, the air
outlet member 61 is disposed on one side of an integral body formed
by the atomizing groove 31 and the heating groove 41, and is
located between the first side 311 and the second side 411.
[0093] In this embodiment, the communication groove 8 is disposed
on one side of an integral body formed by the atomizing groove 31
and the heating groove 41, and the air outlet member 61 is provided
on the other side of the integral body formed by the atomizing
groove 31 and the heating groove 41. In this way, the air ducts and
the communication grooves 8 are disposed on two sides of the
integral body formed by the atomizing grooves 31 and the heating
grooves 41, so that the arrangement is quite reasonable, and the
internal space of the humidifying device shell 10 is saved.
[0094] Still referring to FIG. 8, the seat 2 is further provided
with a water groove 7 configured to supply water to the heating
groove 41 and the atomizing groove 31, and an opening of the water
groove 7 faces the side where the water tank 1 is located. The
water groove 7, the atomizing groove 31, and the heating groove 41
are arranged in sequence, that is, the atomizing groove 31 is
arranged between the water groove 7 and the heating groove 41. The
atomizing groove 31 is open toward one side of the water groove 7
and is directly communicated with the water groove 7. A
communication groove 8 is disposed between the heating groove 41
and the water groove 7.
[0095] Referring to FIG. 7 and FIG. 10, the third opening 423
provided in the cover 42 is disposed aligned with the communication
groove 8, one end of the communication groove 8 is communicated
with the water groove 7, and the other end of the communication
groove 8 is communicated with the heating groove 41 through the
third opening 423, so that the heating groove 41 and the water
groove 7 are communicated with each other through the communication
groove 8.
[0096] As illustrated in FIG. 12, a water barrier component 81 is
disposed in the communication groove 8, the water barrier component
81 includes at least two water barriers 82, the water barriers 82
are arranged at intervals along an extending direction of the
communication groove 8, and one end of each water barrier 82 near a
bottom of the communication groove 8 is provided with a water
passing hole 83 for water to flow through. An opening area of the
water passing hole 83 is less than or equal to that of the third
opening 423 of the cover 42, so that the water passing hole 83 can
function as a flow restriction on water.
[0097] In this embodiment, the water passing holes 83 of two
adjacent water barriers 82 are disposed in a staggered manner. The
staggered position may be understood as the direction in which the
connection line between the two adjacent water passing holes 83 is
located is inclined with respect to the extending direction of the
communication groove 8 located in the portion between the two water
barriers 82. The water passing holes 83 of two adjacent water
barriers 82 may alternatively not be disposed in a staggered
manner.
[0098] To facilitate the installation of the water barrier 82, the
water barrier component 81 further includes a mounting member 84,
which can be accommodated in the communication groove 8 and has a
shape adapted to the shape of the communication groove 8. A
mounting groove 85 is provided in the mounting member 84, and the
water barriers 82 are fixedly disposed in the mounting groove 85
and sequentially arranged along the extending direction of the
mounting groove 85. The water passing hole 83 of the water barrier
82 is disposed close to the opening of the mounting groove 85. When
the water barrier component 81 is mounted in the communication
groove 8, the opening of the mounting groove 85 is disposed toward
the bottom of the communication groove 8.
[0099] By disposing the water barrier component 81, the amount of
water flowing into the heating groove 41 from the water groove 7
can be controlled, to prevent the boiled water in the heating
groove 41 from flowing back into the atomizing groove 31, thereby
causing the atomizing sheet in the atomizing groove 31 to be
damaged due to an increase in temperature. In addition, an integral
body formed by the mounting member 84 and the water barrier 82 is
mounted in the communication groove 8, and the water barrier 82 can
be conveniently removed, cleaned, and replaced.
[0100] The following describes the working principle of the
humidifying device of this embodiment as a whole.
[0101] The water in the water groove 7 enters the atomizing groove
31. The atomizing groove 31 atomizes the water. The air flow is
blown out from the first air outlet 611 of the air outlet member 61
to form a first air flow and enters the first air duct 51. The
first air flow enters the muffler 32 through the first ventilation
hole 324 and the second ventilation hole 326 of the muffler 32 to
form an atomized air flow and then enters the mist outlet channel
11 through the fifth opening 322.
[0102] At the same time, the water in the water groove 7 enters the
heating groove 41, the heating groove 41 heats the water, the air
flow is blown out from the second air outlet 612 of the air outlet
member 61 to form a second air flow into the second air duct 52,
the second air flow enters the atomizing cavity 3 from the second
air duct 52 through the first opening 421 in the cover 42 to form a
heated air flow, and the heated air flow enters the mist outlet
channel 11 from the third opening 423 in the cover 42.
[0103] Further, the atomized air flow and the heated air flow are
mixed in the mist outlet channel 11 and are finally sprayed out
from the humidifying device.
[0104] The humidifying device of the first embodiment of the
present invention is shown above and a humidifying device of a
second embodiment is further provided.
[0105] The structure in this embodiment is substantially the same
as that in the first embodiment. As illustrated in FIG. 13, the
difference is merely lies in that the communication groove 8 is
further provided with a water level measurement apparatus 86,
configured to measure a water level in the communication groove
8.
[0106] Since the water in the heating groove 41 is supplied by the
water groove 7 and the water groove 7 is disposed closer to the
atomizing groove 31 as compared with the heating groove 41, it is
inevitable that there may be water in the atomizing groove 31
first. When there is no water in the heating groove 41, in this
embodiment, the water level measurement apparatus 86 is disposed in
the communication groove 8 instead of in the water groove 7, so as
to prevent the situation in which the humidifying device starts to
operate when there is water in the atomizing groove 31 close to the
water groove 7 and there is no water in the heating groove 41, thus
causing dry burning in the heating groove 41.
[0107] Preferably, the water level measurement apparatus 86 is
provided closer to the heating groove 41 as compared with the water
groove 7.
[0108] The water level measurement apparatus 86 is disposed between
two adjacent water barriers 82. By disposing the water level
measurement apparatus 86 between two adjacent water barriers 82,
the measured water level is ensured to be the water level after
flow restriction through the water passing hole 83 and is less
affected by water level fluctuations in the water groove 7 and the
heating groove 41.
[0109] In this embodiment, the water level measurement apparatus 86
includes a reed tube and a floating ring sleeved on the reed tube,
and the reed tube is fixedly disposed at the bottom of the
communication groove 8. The water level measurement apparatus 86
may alternatively not be in the form of a reed tube or a floating
ring or may be in other ways and is not specifically limited
herein.
[0110] Referring to FIG. 14, when the mounting member 84 is
provided, the wall surfaces of the two water barriers 82 between
which the water level measurement apparatus 86 is provided and the
mounting member 84 between the two water barriers 82 are disposed
in a circular shape, so as to facilitate the placement of the water
level measurement apparatus 86.
[0111] An embodiment of this application further provides a
humidifying device according to a third embodiment.
[0112] Referring to FIG. 15, the structure of this embodiment is
substantially the same as that of the second embodiment, and the
difference merely lies in that the air blowing apparatus further
includes a waterproof component 62.
[0113] As illustrated in FIG. 16, the waterproof component 62
includes a waterproof member 63 and an elastic support member 64.
The waterproof member 63 is supported on the elastic support member
64 and covers air outlets of the air outlet member 61 for air
discharging. The air outlets are the first air outlet 611 and the
second air outlet 612. The waterproof member 63 is movable under a
force to open the air outlet and enable the elastic support member
64 to be deformed; and after the force applied to the waterproof
member 63 is removed, the elastic support member 64 recovers
deformation to drive the waterproof member 63 to move until
covering the air outlet.
[0114] The air blowing apparatus is disposed on the seat 2. The
waterproof member 63 includes a waterproof portion 631 for covering
or blocking an air outlet position of the air outlet member 61 and
a connection portion 632 connected to a side of the waterproof
portion 631. One end of the elastic support member 64 is abutted on
the seat 2, and the other end of the elastic support member 64 is
abutted on the connection portion 632. The waterproof component 62
further includes a guide member 65. The guide member 65 is disposed
around an outer side of the elastic support member 64, to provide
guide for movement of the elastic support member 64 or the
connection portion 632.
[0115] The guide member 65 in this embodiment is fixedly disposed
on the seat 2, and the elastic support member 64 is a spring
disposed in the guide member 65. A first guide hole 634 is formed
in the guide member 65.
[0116] The waterproof portion 631 is U-shaped and has a connecting
wall (not numbered) and a blocking wall (not numbered) extending
toward the same side opposite to the connecting wall. The
waterproof portion 631 covers part of a circumferential surface of
the air outlet member 61, and the two blocking walls respectively
cover the first air outlet member 611 and the second air outlet
member 612.
[0117] The connection portion 632 is connected to the connecting
wall, and a guide section 633 is disposed on the side facing the
seat 2. The guide section 633 is inserted into the first guide hole
of the guide member 65 and abuts on the elastic support member 64.
The guide section 633 is adapted to the shape of the first guide
hole 634 of the guide member 65 and can move along the length
direction of the guide member 65.
[0118] The waterproof member 63, the elastic support member 64, and
the guide member 65 are coordinated in a variety of ways, which is
not specifically limited herein. FIG. 17 illustrates another
coordinating manner of the waterproof member 63, the elastic
support member 64, and the guide member 65. In the coordination
mode, the connection portion 632 does not include a guide section
633, and instead, a second guide hole 635 is provided on the side
away from the water tank 1. The elastic support member 64 is
partially accommodated in the second guide hole 635, and the
connection portion 632 is accommodated in the first guide hole 634,
so as to be slidable along the length direction of the guide member
65. In this case, one end of the elastic support member 64 is
abutted on the bottom wall of the first guide hole 634, and the
other end of the elastic support member 64 is abutted on the bottom
wall of the second guide hole 635. In the implementation, at least
part of the surface of the connection portion 632 is shaped to fit
with the first guide hole 634 of the guide member 65, so that the
connection portion is movable along the length direction of the
guide member 65.
[0119] The side of the air outlet member 61 away from the seat 2 is
further provided with a limit member 66, which is fixedly disposed
on the air outlet member 61 to prevent the waterproof member 63
from being separated from the air outlet member 61. Specifically,
the limit member 66 has a cover-like structure, which is covered on
the air outlet member 61, and part of the inner wall surface of the
cover-like structure is in interference fit with part of the
circumferential surface of the air outlet member 61. However, there
are many ways of fastening the limit member 66 and the air outlet
member 61, which are not specifically limited herein.
[0120] Referring to FIG. 18, in order to facilitate the application
of force to the waterproof member 63 when the water tank 1 is
placed on the seat 2, a protrusion (not numbered) may be provided
at a position corresponding to the waterproof member 63 on the
water tank 1, and the force is applied to the waterproof member 63
through the protrusion. In a preferable embodiment, a force is
applied on the waterproof member 63 by using the air duct partition
53.
[0121] Specifically, one of the air duct partitions 53 is disposed
aligned with the waterproof member 63 and more specifically with
the connection portion 632 of the waterproof member 63. A notch 58
is provided in an air duct partition 53 aligned with the waterproof
member 63 for receiving the waterproof member 63 when the air
outlet member 61 extends into the air duct 5.
[0122] In this embodiment, the waterproof member 63 is provided to
prevent water from entering into the seat 2 from the air outlets
(the first air outlet member 611 and the second air outlet member
612) during the process of cleaning the seat 2 of the humidifying
device. Since the circuit board is provided in the seat 2, the
short circuit of the circuit board due to humidity can be
prevented, and the service life of the circuit board can be
prolonged. At the same time, the elastic support member 64 is
further provided, so that when the water tank 1 is placed on the
seat 2, the water tank 1 can press the waterproof member 63 to move
toward the side where the elastic support member 64 is located, so
that the elastic support member 64 is deformed, and the air outlet
is opened, which is convenient to operate.
[0123] An embodiment of this application further provides a
humidifying device according to a fourth embodiment.
[0124] The structure of this embodiment is substantially the same
as that of the first embodiment, and the difference merely lies in
that the air blowing apparatus further includes a waterproof
component 62. The structure of the waterproof component 62 has been
described in the third embodiment and is not described herein.
[0125] To sum up, by disposing the first air duct 51 and the second
air duct 52 in the humidifying device of this application, the air
flow from the air outlet member 61 does not appear turbulence, and
the water steam and water mist can be quickly mixed, so that the
mist discharge efficiency is high. Moreover, because the air flow
from the air outlet 61 does not have turbulence, the temperature
uniformity of the mist discharged from the humidifying device is
better. In addition, the humidifying device of this application is
provided with a second air duct 52 communicated with the heating
cavity 4, to enable the humidifying device to have an independent
air duct to blow out the water steam generated by heating at the
heating cavity 4 to the mist outlet channel 11, so that the water
mist atomized in the atomizing cavity 3 can be quickly heated when
the humidifying device starts operating, that is, the hot mist can
be quickly discharged. At the same time, there is a large amount of
hot mist in the continuous operating process of humidifying
device.
[0126] The foregoing embodiments are merely illustrative of several
implementations of this application and the description thereof is
more specific and detailed, but cannot therefore be construed as
limiting the scope of this application. It should be noted that
several modifications and modifications may be made by those of
ordinary skill in the art without departing from the concept of
this application, all of which fall within the protection scope of
this application. Therefore, the protection scope of this
application shall be subject to the appended claims.
